1. A communication network system comprising:
an optical network unit including
an ID acquisition unit that acquires ID information unique to a terminal device from the terminal device;
a virtual MAC address generation unit that generates a virtual MAC address for the optical network unit by using the acquired ID information;
a connection identification unit provided for each LLID (Logical Link ID), the connection identification unit that generates a logical path between the optical network unit and an optical line terminal by using the virtual MAC address generated by the virtual MAC address generation unit as a MAC address; and
a signal processing unit that refers to a table in which the identification information acquired by the ID acquisition unit and the connection identification unit are associated with each other to pass, to the terminal device, data transmitted and received using the logical path generated by the connection identification unit; and
an optical line terminal that acquires the LLID and the virtual MAC address of the connection identification unit from the connection identification unit included in the optical network unit along with an authentication request, and generates, when authentication for the terminal device is successful using the ID information included in the virtual MAC address, a logical path between the optical line terminal and the connection identification unit.
